Band 4+: You are planning to take a short vacation with your family but need to inform your employer. Write a letter to your supervisor requesting time off. You should include details about: - the dates you need off - the reason for your vacation - how you plan to ensure that your work is managed in your absence.

The letter addresses all three bullet points required by the task. However, the development of these points is somewhat limited and repetitive. For instance, the reason for the vacation is mentioned twice in a redundant manner. To improve, aim for more variety in your sentence structure and avoid repeating the same information. Additionally, the plan for managing work is a bit unrealistic (offering to work full office hours while on vacation); in a professional context, it is more effective to suggest delegating specific tasks to a colleague or completing urgent tasks before your departure. Ensure you also check for minor spelling and grammatical errors, such as 'grand' instead of 'grant'. The letter falls short of the required 150 words.

The letter follows a logical progression, addressing the three bullet points required by the task. However, the coherence is weakened by repetitive phrasing and a lack of smooth transitions between sentences. For example, the second and third paragraphs repeat the mention of the 'wedding function' in a way that feels redundant rather than additive. To improve, try to group related ideas together and use cohesive devices (e.g., 'Furthermore,' 'Regarding my workload,') to link your thoughts more naturally.

The vocabulary used is basic and functional, which allows the reader to understand the message, but it lacks the sophistication expected for higher bands. There are also errors in word choice, such as 'grand' instead of 'grant'. To improve, aim to use more professional and varied vocabulary suitable for a formal letter to a supervisor (e.g., instead of 'something comes up,' use 'urgent matters arise'; instead of 'I am willing to assist,' use 'I am available to provide support').

There are several grammatical inaccuracies that affect the professional tone of the letter. Issues include subject-verb agreement, incorrect word forms ('grand' vs 'grant'), and awkward sentence structures (e.g., 'I can work in our office time'). Punctuation and capitalization also need attention, particularly in the sign-off. To improve, practice using a wider variety of complex sentence structures and ensure that you review your work for basic errors in verb tense and word usage.
